How to fish it · for Grayling
When
Midday window — grayling feed best from late morning into early afternoon.
Where
Work runs and glides — grayling shoal in the bottom third of the water column.
Method
Tight-line nymph the bottom third with weighted patterns.
Kit
10 ft #3 rod, floating line, long leader to 4 lb fluoro for nymphs.
Why this works
Good — water clarity is right today, though insect activity could be better.

About this water
Water quality (WFD)
- Ecology: Good
- Chemical: Failing to achieve good
What this classification means
WFD re-coded 2026-09-14 after the pin audit: matched by point query against EEA WISE WFD2022_SurfaceWaterBody (the river water body whose line lies 3 m from the venue pin). Status: WISE 2022 (3rd RBMP) ecological class 2 = Good, chemical 'failing to achieve good' (Austria-wide in the 2022 cycle). Prior id ATOK301630005 (High) described a different reach.

What would change the calculation
Warmer water — toward the 4–14 °C ideal band — would lift the temperature score.
The dawn and dusk windows score higher than the midday lull.

Seasons & zones
- Trout 1 May → 30 September
- Grayling 16 May → 31 March
Austrian grayling (Äsche) rules are state and fishery specific. Common pattern: closed 1 January – 31 May (spawning protection); open from June. Individual fishery seasons often end October/November. Always check the local Fischereikarte and specific water permit. Salzburg-area waters commonly show 1 June or 16 May opener.
Season dates are set at state or regional level — confirm the local rules.
